I trust web authors to understand what z is for. w might be a bit more difficult but might not even be necessary to specify. If we add a new element into the web platform we should think beyond the current needs. I believe that this interface would be useful for other situations like 3D transforms or WebGL contexts. Especially CSS Transforms have a lot of situations where you get from a 2D context into a 3D context. You may would need to return different object types depending on the current transformation, this seems to be difficult in the long term.
